14.14 The piston in the cylinder head of a locomotive has a stroke (twice the amplitude) of 1.0 m. If the piston moves with simple harmonic motion with an angular frequency of 200 rad/min, what is its maximum speed?


Given in the question that:
Angular frequency of the piston, ω = 200 rad/ min. 
Stroke=1.0amplitude, A=1.02=0.5 m
The maximum speed (vmax) of the piston:
vmax=
       =200×0.5=100 m/min
